Understanding rare event formation and ultrafast dynamics in chip-scale nonlinear oscillators: Spectro-temporal signatures of higher-order rogue solitons and sub-cycle synthesis
Abstract
Nonlinear second- and third-order parametric processes in chip-scale high quality factor (Q) resonators provide a robust and exciting platform to understand ultrafast dynamical processing. Seeded by spontaneous noise, parametric regimes such as modulation instability, Turing patterns, dissipative solitons, and chaos have been observed. These chip-scale nonlinear oscillators -- spanning over thousands of coupled and phase-locked frequency modes further provide a fertile ground for understanding pattern and rare event formation, along with their concurrent ultrafast dynamics. These have impact in Navy applications from fundamental clocks for RF and optical communications, synchronization and timing transfer between clock-to-clock, the absolute definition of the optical frequency standard, microwave (radar X-band) to optical clockwork, ultrafast chaos generation for secure communications, and high-power laser synthesis and spectroscopy. In this program we propose to advance two associated experimental efforts: (Thrust I) examining and understanding the ultrafast spectro-temporal signatures of higher-order rogue solitons, and (Thrust II) the octave-level fewfemtosecond nonlinear comb oscillator synthesis.
